Looking at Ross Ulbricht's application for citizenship in Dominica and you'll find his mail: rossulbricht@gmail.com

Searching for this mail in the leaked Adobe database and you get one hit:
+-----------+------------------------+--------------------------+------+
|     Id    |          Mail          |           Pass           | Hint |

Because Adobe encrypted the password in ECB mode, I can see that the length of the password is exactly 8 char long [1].

His password encrypted: \x15\x17\x80\xD7\x2D\xC8\x58\xE7
"\x00 + padding" block: \xE2\xA3\x11\xBA\x09\xAB\x47\x07

However searching for anyone with the same password comes up empty (he must have used a "strong" password), so unless someone finds the key Adobe used to encrypt his password, we will never know what password he used.

[1] If the length of his password was less than 8 char, then there would only be one block, and if the length of his password was longer than 8 char, then the last block would look different (compare the last part of his password with the last part of the most used passwords: http://stricture-group.com/files/adobe-top100.txt and you'll see).
